Abstract: Ions are electrochemically removed from an aqueous solution by establishing an electrochemical cell wherein the solution, as cell electrolyte, is caused to flow between a working electrode that includes an ion exchange material and a second electrode that optionally includes an ion exchange material. The polarity of the cell is repeatedly reversed so that ions are successively adsorbed and desorbed at the working electrode and optionally also at the second electrode. Thus, an ion for removal such as Cs.sup.+ may be selectively removed in the presence of a much larger concentration of a second ion such as Na.sup.+.

Abstract translation: 通过建立电化学电池，从水溶液中电化学除去离子，其中使电解质溶液在包括离子交换材料的工作电极和任选地包括离子交换材料的第二电极之间流动。 电池的极性被重复地反转，使得离子在工作电极和任选地也在第二电极处被连续地吸附和解吸附。 因此，可以在存在更大浓度的第二离子如Na +的情况下选择性地除去诸如Cs +的去除离子。

Abstract: A system and method for providing mobile or temporary water treatment involving ion exchange resins includes a service center, one or more treatment vehicles, a resin transfer hub and one or more resin transport vehicles. The service center can be used to regenerate one or more types of ion exchange resins. The treatment vehicle carries water treatment equipment including a tank holding ion exchange resin. The resin transfer hub facilitates moving resin between a treatment vehicle and a resin transport vehicle. The resin transport vehicle is adapted for carrying resin by one or more of land, sea and air between the resin forwarding center and the service center. In operation, a treatment vehicle brings resin requiring regeneration to the resin transfer hub, where it is emptied and then re-filled with regenerated resin. Resin requiring regeneration is transferred to a resin transport vehicle for transport to the service center. The resin transport vehicle is re-filled there with regenerated resin, which is taken back to the resin transfer hub for transferred to a treatment vehicle.

Abstract: Provided are electrochemical devices that are rechargeable, where the regeneration techniques are based on a batchwise application of current or current density to the cells, where there are a service mode where no current or current density is applied and a recharge mode where a current or current density is applied. Electrochemical and EDI systems according to the embodiments herein are suitable for deionization and/or purification of typical municipal tap quality water in applications where demand for purified, low-TDS water is intermittent. Such operations avoid the use of chemical additions for regeneration purposes. In addition the cells provided herein are amenable to small footprints for consumer and commercial applications such as: dishwashers, washing machines, coffee and espresso makers, ice makers, steam tables, car wash water sources, and steamers.
